To make a 0.02 M solution of EDTA (ethylenediaminetetraacetic acid), first determine the desired final volume of the solution. For example, if you want to prepare 1 liter, weigh out 7.45 grams of disodium EDTA (the disodium salt form is commonly used). Dissolve this in distilled water, then dilute to the final volume of 1 liter. Ensure to mix thoroughly for complete dissolution.

If it's the BPT-002 one, from the very first wave of tins, then it might get a few £ from a collector. If it's YAP1-EN003, this was included in every anniversairy pack, and was mass printed to such an extreme that it's technically worthless.
What are the chelating agents?
Chemicals that combine with metal ions and remove them from their sphere of action, also called sequestrants. They are used in food manufacture to remove traces of metal ions which might otherwise cause foods to deteriorate and clinically to reduce absorption of a mineral, or to increase its excretion; e.g. citrates, tartrates, phosphates, and EDTA
How many grams of EDTA do you add to make a 3.7 percent EDTA solution?
To make a 3.7% EDTA solution, you would add 3.7 grams of EDTA to 100 mL of solution.
When edta is insoluble in distilled water then how to make 0.01N edta solution?
use heat to heat the solution and add EDTA slowly to dissolve it.
How do you prepare 5mM EDTA of 100ml solution?
5mM = 0.005 moles 100 mL = 0.1 Liters Molarity = moles of solute/Liters of solution 0.005 M EDTA = X moles/0.1 Liters = 0.0005 moles EDTA =_____________ Now, look up the molecular formula for EDTA and find how many grams needed to add to your 100 mL.
How can you prepare 100mM EDTA?
To prepare 100mM EDTA solution, dissolve 37.2g of EDTA disodium salt dihydrate in 1 liter of water. Make sure the pH is adjusted to around 8.0 with sodium hydroxide or hydrochloric acid if needed. Mix well until EDTA is fully dissolved.
How do you can prepare 0.5molar EDTA solution?
To prepare a 0.5 M EDTA solution, dissolve the appropriate amount of EDTA disodium salt dihydrate (molecular weight 372.24 g/mol) in water to achieve a final volume desired. For example, to make 100 mL of 0.5 M EDTA solution, you would dissolve 18.61 g of EDTA disodium salt dihydrate in water and adjust the volume to 100 mL.
How much quantity of EDTA dissolved in 1000ml to get 0.01 m solution of EDTA?
To prepare a 0.01 M solution of EDTA in 1000 ml, you would need 37.22 grams of EDTA disodium salt dihydrate (C10H14N2Na2O8·2H2O) or approximately 0.1 moles. Dissolve the EDTA in water and make up the volume to 1000 ml to get a 0.01 M solution.
How much gm of disodium edta require to prepare 0.05 m disodium edta solution?
To prepare a 0.05 M disodium EDTA solution, you would need to dissolve 3.72 grams of disodium EDTA dihydrate (Na2C10H14N2Na2·2H2O) in enough water to make 1 liter of solution.
Why edta is secondary stadard?
EDTA (ethylenediaminetetraacetic acid) is not a secondary standard. It is a chelating agent commonly used as a titrant in complexometric titrations to determine metal ions in solution. The stability and selectivity of EDTA complexes make it a primary standard for this purpose.
How do you prepare 1mM EDTA from 0.1M EDTA?
0.1M is 1/10 molar whereas 1mM is 1 millimolar and thus 1/1000 molar. There is thus a 1:100 dilution. So 10:1000 would be the same. To a 1000ml volumetric flask, pipete 10mls of 0.1M EDTA solution. Make up to the mark with deionized water. Mix and shake and you will have 1000mls of 1mM EDTA solution.
What is the purpose of standardizing EDTA in Complexometric titration?
Standardizing EDTA in complexometric titration is done to determine its exact molarity or concentration. This is important because the accuracy of the titration results depends on knowing the precise concentration of the EDTA solution being used. By standardizing EDTA, any errors in concentration can be corrected, ensuring accurate and reliable results in the titration process.
What is greater 002 or 020?
002 is 2 and 020 is 20, so 020 is greater.
